supported display resolutions for iMX6 solo/dual lite?

We have an LCD display which runs at HD resolution of 1080x1920 interfaced via MIPI. Currently it's connected to an iMX6 dual core processor via a parallel-to-MIPI bridge (because the iMX6 MIPI interface does not support the LCD's display resolution). Our testing has revealed that we only need a single processor and have disabled one of the cores to save on power consumption. To save on costs, I'm looking at the solo or dual-lite chips to see if they could be used for our purposes (they are pin-compatible, according to the feature set).

 

According to the product summary pages for both solo and dual lite;

both chips only support display resolutions upto 1366x768 (thus, not suitable for my purposes).

 

But, according to the "iMX6 Solo/Dual lite Applications Processor Reference Manual" , section 38.1.2.1.2.2 Display Interface (pages 2793 - 2795) mentions,

 

For synchronous access with one cycle/pixel, this enables, e.g (including 35% blanking

intervals)

1080p (1920x1080) @ 60 fps

i.MX 6Solo/6DualLite Applications Processor Reference Manual, Rev. 1, 04/2013

Freescale Semiconductor, Inc.

Chapter 38 Image Processing Unit (IPU)

• WSXGA+ (1680x1050) @ 60 fps

• The combined rate for the two ports is up to 240 MP/sec

The interface includes the following additional features:

• Screen size: up to 4096 x 2048 pixels, programmable by software.

• Scan Order: progressive or interlaced

• Synchronization

• Programmable horizontal and vertical synchronization output signals (for

synchronous access)

• Data enabling output signal

• Software contrast control using 8-bit programmable pulse-width modulation (PWM)

Two dedicated PWM outputs are provided

 

So, I'd like some clarity on this matter - do the solo/dual-lite processors support 1080 HD resolution? If not, what is the datasheet referring to?

 

Puzzled,
